Raspberry Pi Pi-GPIO User Guide

Overview

This is an I/O expansion kit designed for Raspberry Pi, which provides 4 sets of 2x20 pinheaders, that means a handy way to "stack" multi different HATs together, and use them as a specific combination / project.

Features

Standard Raspberry Pi connectivity, directly pluggable OR through ribbon cable
4 sets of 2x20 pinheaders, connect multi HATs together
Clear and descriptive pin labels for easy use
Reserved jumper pads on the bottom side, pin connections are changeable by soldering, to avoid pin conflicts

Note: make sure there are no any pin conflicts between the HATs you want to use together before connecting.
